The experiment was intended to show that the dog will eat the tastier food advertised on TV at a faster rate than it eats its regular food.

An experiment must have an independent variable and a dependent variable. The dependent variable is the variable that is being manipulated in the experiment. The responding variable is also called the dependent variable.

Antigen-presenting cells usually display processed antigens to T cells in the LYMPH NODES. These nodes are regions of the body where lymphocytes are activated.

T cells are white blood cells (lymphocytes), which form part of the immune system.

These cells (T cells) develop in the bone marrow.

The lymph nodes are secondary lymphoid organs in which naive T cells that search for specific antigens examine antigen-presenting cells (APCs) for their activation.

Answer:

Adenosine Triphosphate

Explanation:

Answer:

1. Protein - build lean muscle and strengthen tendons

2. Lipids - insulation and long-term energy

3. Carbohydrates - provides quick, easily digested energy

4. Nucleic Acids - repair and replicate DNA and RNA

Explanation:

a. Think of protein as what helps your muscles grow and strengthen

b. Think of lipids as fats (blubber, the extra fat, helps insulate seals from the cold)

c. carbohydrates are found in starch and bread products, and are used to help build up energy prior to marathons.

d. nucleic acids -  think of nucleus; it is where genetic material is located, and also where DNA and RNA is located.

Answer:

ribosomes and cell membrane

Explanation:

Prokaryotes are not allow to have nucleus. They have free roaming DNA, so only ribosomes and cell membrane can be both.

Of the annual global total of fixed nitrogen, human activities account for roughly 45%.

Nitrogen fixation is the global amount of nitrogen that gets assimilated by any living organism into another organic compound. The organic compound can be ammonia or nitrogen ions.

Of the total global annual nitrogen fixation, humans account for a great amount. The current estimation is that humans cause 45% of the nitrogen fixation annually. The leading causes of this high rate are the burning of fossil fuels and increased agricultural fertilizer use.

Answer:

Okay so for A the thing that is wrong with this experiment is that Cindy has done quite a few things incorrectly. Firstly what her experiment was about. Being healthy is a good thing but then turning around and doing the exact opposite for a week can damage your body. Secondly, Running 4 miles after school is good but then for the next week she sits and watches tv for 3 hours. It doesn't make sense on how she measured her experiment. Cindy should have recorded the times when she ran four miles and then used the same time to watch Tv for the next week.

We can fix this experiment by maybe taking out the hot Cheetos from it as that's just not healthy. Secondly we can have Cindy record how many minutes/hours she ran in the 4 miles and use those same times to watch Tv so that it's even.

Explanation:

For part B firstly it's just not possible to predict the weather with your feet. Secondly your grandpa could easily lie and tell you their hurting or they could just always be sore. Lastly, His feet could be not sore and it still rains.

We can fix this experiment by may be doing something more realistic. But to stay on this instead of calling him you should maybe stay over so that in the morning you can tell whether or not his feet are sore then record for the rest of the day to see if it rains or not. If their not sore and it rains then we know he can't predict weather with his feet the same goes for if they were sore and didn't rain.

Answer:

What is osmosis? Why are they assuming the large molecules will stay on their own side of the membrane? The membrane is semipermeable, so the membrane only allows some molecules through and not others. In this case, it doesn't allow the large molecules through.

Explanation:

Hope It Helps

It is assumed that the large molecules will stay on their own side of the cell membrane because the membrane is semipermeable which only allows the passage of some molecules in and out of the membrane.

A cell membrane may be defined as a type of biological membrane that significantly separates and protects the inner environment of all cells from the outside environment. It is semi-permeable in nature.

The cell membrane consists of a lipid bilayer that is semi-permeable. The cell membrane regulates the transport of materials entering and exiting the cell.

The ability of a molecule to travel across a membrane depends on its concentration, charge, and size. In general, molecules diffuse across membranes from areas of high concentration to low concentration. Cell membranes prevent charged molecules from entering the cell unless the cell maintains an electrical potential.

Answer:

Hypoxia occurs when algae and other organisms die from lack of oxygen and available nutrients. Hypoxia events often follow algal blooms. The cyanobacteria, algae, and phytoplankton sink to the seafloor, and are decomposed by bacteria. This lack of oxygen creates dead zones in which most aquatic species cannot survive.

Answer:By their activity in the soil, earthworms offer many benefits: increased nutrient availability, better drainage, and a more stable soil structure, all of which help improve farm productivity. Worms feed on plant debris (dead roots, leaves, grasses, manure) and soil. ... Nitrogen in the casts is readily available to plants.

Explanation:

Earthworms have the ability to eat and mix large amount of soil and organic matter and deposit it in the form of casts. They also enhance incorporation and decomposition of organic matter, increase soil aggregate stability, improve porosity and water infiltration, and increase microbial activity.

Plants use magnesium ions to make chlorophyll in their leaves. Like in nitrate deficiency, the plant is limited in terms of its photosynthetic ability and the plant growth is compromised. Magnesium is a limiting factor in healthy plant growth.

Explanation:

The pulmonary valve (sometimes referred to as the pulmonic valve) is a valve of the heart that lies between the right ventricle and the pulmonary artery and has three cusps. It is one of the four valves of the heart and one of the two semilunar valves, the other being the aortic valve. Similar to the aortic valve, the pulmonary valve opens in ventricular systole, when the pressure in the right ventricle rises above the pressure in the pulmonary artery. At the end of ventricular systole, when the pressure in the right ventricle falls rapidly, the pressure in the pulmonary artery will close the pulmonary valve.

Answer:

This actually depends, since most of our water is filtered (depending on where you live) then yes it is sustainable! But if our water wasn't filtered then no, it would not be sustainable. This is because of all the things that go into our water before it's filtered. We've got plastic, trash, dead fish and all that, in some cases sewer system drainage and a lot more that goes into the filtered water that we drink.
